PowerPlant 15

Purify, protect, regulate, and rebuild unrestricted new power from old with the P15, our second most powerful AC regenerator.

The DirectStream P15 Power Plant is the gold standard for safety, reliability, and high-performance AC power regeneration. The P15 improves micro and macro dynamics, audio purity, instrumental separation, soundstage width and depth, and lowers background noise for any connected equipment. From medium to large power amplifiers to the smallest pieces of source equipment, the P15 will work magic on your system’s performance. Don’t starve your music or risk damaging your equipment. A P15 gives you greatly improved performance and safety from just plugging into the wall socket and far better dynamics, bass and a much bigger, open soundstage than any power conditioner on the market.

DESIGN

The P15 features an ultra-low impedance analog power amplifier, FPGA based sine wave generator based on pure, clean, analog DSD (PCM), 10 outlets (US version) across 5 separate regenerated zones, and 1/4" thick copper busbars that deliver regenerated power to each receptacle. Through regeneration, the P15 creates a completely new AC waveform that adds missing energy back onto the power line to correct for serious issues, such as distortion and voltage fluctuations.

APPLICATION

With a maximum output of 1500 watts, the P15 regenerates steady, regulated, pure AC that is unaffected by your equipment's demands for power. Powering your system from the outlets of the P15 will reveal new voices, new harmonics, and a renewed sense of musicality. As the gold standard for safety, reliability, and high-performace AC power regeneration, the P15 will ensure you receive the same great performance every time you listen and provide a firm foundation for your system.

Technology

OVERVIEW

The DirectStream Power Plant 15 is the next generation of AC power regeneration. It has 5 separate regenerated zones, buss bar delivery system, and 1500 watts of pure regenerated power. From medium to large power amplifiers to the smallest pieces of source equipment, the P15 will work magic on your system’s performance. Expect far better micro and macro dynamics as well as a cleaner, lower noise background. Power regeneration uses active components, like those found in large, powerful audio amplifiers, to rebuild the AC power and produce clean, clear, distortion-free, regulated AC to the equipment. The results are dramatic: unrestrained dynamics even under the loudest passages, an open, wide soundstage that does not collapse with volume and a naturalness to the music that is remarkable. The 7-inch, full color display on the front panel of the P15 allows you to measure distortion, both incoming and outgoing, improvement levels, and power consumption. You can also adjust your settings, such as the turn on/off sequence and the output voltage, as well as turn individual zones on or off, and measure the power quality with either the built-in oscilloscope or the THD analyzer.

OUTPUT

The P15 takes in your home's noisy, distorted, and unregulated AC and outputs pure and perfect power that dramatically enhances sound quality. It does this by rebuilding the AC, lowering output impedance, and regulating the voltage. Low output impedance is critical to maintaining a dynamic presentation. Powering equipment through a passive power conditioner only worsens the problem and should be avoided. The Power Plant, on the other hand, has such low output impedance (0.008Ω vs. typical 0.4Ω) that even the hungriest of amplifiers won’t be starved for clean AC power. When your amp is asked to produce loud orchestral levels, you want to make sure it has all the power it needs and only a Power Plant provides a constant output regardless of the dynamic demands of equipment or your neighbors. Power Plants also generate new waveforms that enhance the capabilities of your equipment. MultiWave extends the peak charging time of the sine wave so connected equipment has more energy storage and less power supply ripple. The results are dramatic: a bigger more musically accurate soundstage than with a simple sine wave.

PROTECTION

An electrical surge, or spiked transient, is an intense, short-duration voltage increase that travels through electrical wiring in our homes. It can severely damage connected equipment. Shielding devices from these potential electrical problems is mandatory if we're to protect our investment and ensure the safety of our homes. These electrical transients are not the only potentially damaging problems faced by our sensitive audio systems. There are also sustained over-voltage conditions that many surge suppression devices will not be able to protect equipment from. Owners who have invested in a Power Plant can rest assured their connected equipment will be safe from any power line event such as over voltage, under voltage, surges, spikes and potentially threatening problems. The input voltage to the Power Plant is fully protected by state-of-the-art clamping devices and the output of the Power Plant is fully regulated so even large voltage swings that would normally damage connected equipment are made safe by either clamping or regulating. In most cases, connected equipment enjoys the protection and performance benefits of fully regulated power, even under extreme circumstances.

Reviews

I was shocked at how many albums in the junk bin became much more enjoyable. The amount of low level detail revealed by clean power is incredible. That alone is worth the price asked of the P15. Imagine getting another thousand LPs for free that you now love. What’s that worth to you?

Living in downtown NYC, the juice that flows from my outlets varies literally from hour to hour.
Voltage spikes and sags have been measured with deviations that vary from moderate to, "That can't be right." [With my demanding Class A amps] I needed two P20s, along with the P15 to handle all the other components' power needs.

The effect of all this effort to deliver clean AC power was not subtle. Every aspect of the sound
is touched, elevated, and refined. Everything we seek in great sound, dimension, depth and space, color, dynamics, transparency, and detail are boosted in seeming equal...

Positive Feedback Greg Petan

P20 further improved crispness, expression, and clarity. At this point, the raw power was unlistenable, making the system sound confused, blurred, rough, and shouty

Best flip-flops I've met
Size: 11, Color: Black/Geyser
Right away I was impressed by the thichness and cushioning of these flip-flops. They are not a flimsy piece of rubber under my foot. The sole is more like that of an athletic shoe with layers and an impressive tread. I've always found that my heel sits too much on the back edge of flip-flops, or even over it. So I ordered these just a half size large and they're perfect. The foot cradling allows my heel to sit down inside the flip-flop comfortably and securely. They're not about to fall off. The toe piece (I don't know what it's actually called) is not just the typical round rubber post. On these flip-flops it's nicely shaped and fits comfortably between my toes. The arch support is nice too. They're not just flat. In spite of being more substantial than the cheapies we all know, these remain lightweight. They clearly look better too

Well made
Size: 11, Color: Black/Geyser
The first thing that stands out about the Columbia PFG Castback Flip sandals is the solid build and clean fishing-inspired design. The Black/Geyser color combination looks sharp and matches the product photos well. The straps feel durable and comfortable against the foot, and the footbed has a slightly cushioned feel that makes them comfortable right out of the box. Overall construction feels sturdy, which is what you’d expect from something designed for outdoor or water use. In everyday wear, the sandals are comfortable and easy to walk in. The footbed provides decent grip and support, and the textured surface helps keep your foot from sliding around when they get wet. They work well for casual use, whether it’s around the house, at the beach, or after a day on the water. The lightweight feel also makes them easy to pack for trips or outdoor activities. After wearing them for a while, they hold up well and remain comfortable for daily use. The materials seem durable and the straps stay secure without stretching out. They’re simple, reliable sandals that work well for warm weather, boating, or casual summer wear. Overall, they’re a solid choice for anyone looking for comfortable flip flops with a slightly more rugged outdoor style.

Extremely comfortable with slight roomy fit
Size: 11, Color: Black/Geyser, Size: 11, Color: Black/Geyser
These are easily the most comfortable flip flops I have ever owned. From the moment I put them on, there was no break in period at all. They felt soft, supportive, and ready for all day wear right out of the box. The cushioning is excellent without feeling too soft, and they have a nice stable feel when walking. They are lightweight and clearly made with quality materials, making them great for everyday use or around water. One thing to note is that they run a little on the larger side, so if you are between sizes, you may want to consider sizing down for a better fit. Overall, these are a great combination of comfort, durability, and function. I would absolutely recommend them, especially if comfort is your top priority. (Excuse the teeth marks- my dog unfortunately got ahold of them before I snapped the photo- they are PERFECT out of the box)

I plan to use them more regularly outdoors once the weather warms up. What Worked Well: Immediate Comfort: The footbed feels cushioned and supportive without needing a break-in period. Secure Fit: The straps sit comfortably without rubbing or feeling stiff. Lightweight Design: Easy to slip on and off for quick wear. Clean Style: The black and white combination gives them a sharp, versatile look. Positive Feedback: My wife has already commented on how good they look. Things to Keep in Mind: Seasonal Use: Best suited for warmer weather and casual settings. Sizing: Checking the size guide helps ensure the right fit. Bottom Line: Based on my experience so far, these flip-flops offer a great balance of comfort and style. They’re comfortable enough for everyday wear and look sharp enough for casual outings. I’m looking forward to putting them to full use once spring arrives.

Columbia always makes great stuff
Size: 14, Color: Espresso II/Black
Even with my flat feet these offer a lot of padding which makes these extremely comfortable. They increase my height about an inch haha. These are great for walking around the beach or just going for walks. The tread on the bottom of these make walking up hills where the surfaces are not completely even extremely easy and very grippy. Time will tell how durable these are, but so far they're holding up very well.
